The works involve:
• removal of the worn-out surfacing,
• repairs and/or replacement of the underlying concrete slabs
• resurfacing with an improved surfacing product
• replacement of defective drainage pipes
The works are required as the road surface has reached the end of its serviceable life. Once repairs are complete, the new surfacing will have none of the existing transverse joints which cause unacceptable amounts of noise when trafficked. The work will also significantly reduce any unplanned closures for emergency repairs on this section of the A483.
The work commences on 11/10/21 and lasts for 5 weeks. In order to achieve this programme, the contractor will work in shifts enabling a 24/7 working schedule.
The repair and/or replacement of several concrete slabs, together with the laying of 2 layers of surfacing, will require full closure of each side of the dual carriageway in turn. Therefore, a contraflow arrangement will be set up which will allow the A483 to remain open to one lane of traffic in either direction.
These measures are necessary to protect both the workforce and the travelling public, and to enable the works to be carried out in as short a time as possible.
There will be full overnight closures at certain times within the programme to enable the installation and dismantling of the temporary traffic management system required to undertake the works.
For overnight carriageway closures between Junction 5 and 6, Northbound traffic will leave the A483 at Junction 5 (Mold road interchange) and follow the A541 to the A5152 and then to Junction 6 (Gresford Interchange) where they will re-join the A483. Southbound traffic will leave the A483 at Junction 6 and follow the A5152 to the A541 and then to Junction 5 to re-join the A483.
For overnight carriageway closures between Junction 6 and 7, Northbound traffic will leave the A483 at Junction 6 and follow the B5445 to the B5102 and then to Junction 7 (Rossett interchange) and re-join the A483. Southbound traffic will leave the A483 at Junction 7 and follow the B5102 to the B5445 and then to Junction 6 to re-join the A483.
The routes will be fully signed and patrolled.
In order to complete these works in such a short period of time, there will be overnight working. However, we are working with the contractor to identify the noisiest activities of the works and programme them to be carried out during the day and early evening. The majority of the work operations will be no louder than the normal noise associated with traffic using the dual carriageway on a daily basis.
A scheme was undertaken earlier in the year to upgrade the central reserve crossovers which were necessary to enable the contraflow system to now be placed. Unfortunately, that scheme was delayed by a period of closures for essential repair works undertaken by National Highways on the A483 outside Chester. Additionally, this present scheme could only be started once the school summer holidays had finished.
When the contraflow is in operation certain slip roads will be temporarily inaccessible. Drivers will follow diversion signs along the A483 to one of the other interchanges in order to continue their journey.
Traffic will not be diverted away from the A483 during the contraflow operation. Mitigation measures will be in place, and we will be working closely with WCBC highways department to monitor the situation.
Progress updates will be issued on the Traffic Wales website and on Twitter @TrafficWalesN. These channels will also advise road users about congestion and expected journey times.
The Trunk Road Agent is liaising with Wrexham County Borough Council about the traffic signals in Gresford.
Further resources will be provided to help to ease issues during the scheme as needed.
Traffic will only be diverted through Gresford when overnight closures are in place, which have been limited as much as possible.
The remaining works will be done under lane closures, a contraflow and a diversion via the next junction on the A483.
